CHECKING POWER STEERINGFLUID
63X002a
Check the fluid level on the dipstick. If necessary, add
automatic transmission fluid DEXRONII or III .
If the vehicle has been driven around 80 km/h (50 mph) for 20
minutes (a little more in frigid temperatures), the fluid is hot
(60 C − 80C or 140F − 175F). You may also check the level
when the fluid is cold (about room temperature, 10 C − 30C
or 50F − 85F) if the engine has not been run for about five
hours.

Clean all dirt off the reservoir and look at the fluid level. If the
fluid is cold, the level should be in the “COLD” range. Similarly,
if it is hot, the fluid level should be in the “HOT” range. If th\
e
level is at the low side of the appropriate range, add automatic
transmission fluid DEXRON
II or III to bring the level within
the range.
To remove the reservoir cap, turn it counterclockwise and lift
up. To reinstall it, turn it clockwise. After replacing the reservoir
cap, visually check the steering box case, vane pump and hose
connections for leaks or damage.
CAUTION
The reservoir may be hot so be careful not to burn
yourself.

NOTICE
Avoid overfilling, or the power steering could be
damaged.
When adding the power steering fluid, avoid spilling
it. The generator under the power steering reservoir
could be damaged if fluid is spilled on it.
CHECKING SUSPENSION FLUID
AHC
63X007c
1“MAX” line 2“MIN” line
Under the unloaded condition, check the Suspension
Fluid AHC in the following way.
1. Start the engine and put the vehicle height in the “LO” (Low)
mode and then “N” (Normal) mode.
2. Turn off the ignition switch about 30 seconds after the “N”
(Normal) mode indicator light comes on.
3. Make sure the fluid level is between “MAX” and “MIN”.
If the fluid level is lower than “MIN”, have suspension fluid AHC
filled by your Lexus dealer.

Only use the Suspension fluid AHC for the active height
control suspension. If you fill other fluids such as brake
fluid, power steering fluid, engine oil, etc., the active
height control suspension could be damaged.
